Probably they will provide the low level drivers
Yes they will, it's in progress as we speak. Like I said it's only an issue for "system" programmers, IE those who work with the bare metal, most Arduino users will neither know nor care.
For many cost sensitive applications it would be usedful to have just the chip like the LPC810
Yeah, having an ARM in an 8-pin DIP is amazing. Nice job with the Due programmer.
